Let's see... cats, dogs, apes, monkeys, all species of parrot, parakeets, cetaceans, rodents, lagomorphs, corvids, elephants....and that's from 20 seconds thinking. All of those can get bored. Sorry Stars, that's waaaaay more than just 10.
However, no, I don't really think snakes get bored. They work on a much higher level of instinct than most mammals and birds do.
Birds feather pick when bored. It makes them neurotic just like with humans confined with nothing to do. Large cats pace when bored. Also neurotic boredom behaviours. Horses confined to stalls all day will lick the walls/chew on the doors. Again, neurotic boredom behaviours. Rodents also exhibit neurotic boredom behaviours such as over grooming. Elephants rock from side to side for hours as a neurotic boredom induced behaviour.
